Big 12 primer: Week 15

Big 12 schedule makers couldn’t have set things up any better. The conference title will be decided on the final Saturday of the season and three teams enter the day with legitimate hopes to earn the Big 12’s BCS berth. Oklahoma State grabs the berth and a share of the Big 12 title with a victory, while Baylor or Texas could grab an outright Big 12 title with a victory and OSU loss.

Here are a few storylines in the Big 12 in Week 15:

No. 17 Oklahoma (9-2, 6-2 Big 12) at No. 6 Oklahoma State (10-1, 7-1), noon ET (ABC): Bedlam has become much more than an in-state battle. It’s had major Big 12 title ramifications in recent years as the Cowboys have risen to the top half of the conference. And the Sooners always have to be dealt with if any team hopes to secure a Big 12 title ring. This year, OSU features the Big 12’s best defense, an underrated offense and is coming off the Big 12’s most impressive win. But OU quarterback Trevor Knight could be the unknown factor on a chilly day in Stillwater. If Knight plays well, the Cowboys' road to a Fiesta Bowl berth gets tougher.

No. 25 Texas (8-3, 7-1) at No. 9 Baylor (10-1, 7-1), 3:30 p.m. ET (Fox): Baylor hopes to close Floyd Casey Stadium with a bang and Texas wants to prove it's not how you start, but how you finish. A share of the Big 12 title also is on the line for both teams. The Bears offense hasn’t looked as explosive in the past two games, but it still looks like it could explode at any time. But if Texas defensive ends Cedric Reed and Jackson Jeffcoat, who combined for five sacks against Texas Tech on Thanksgiving, continue to be a quarterback's nightmare off the edge, it could become a long afternoon for Bryce Petty.
